Effect of substrate pretreatment on microbial protein production

ABSTRACT

The effect of chemical treatments of sawdust, cane sugar bagasse and corn cobs on microbial protein production was investigated. Treating cane sugar bagasse with 0.2% H2SO4, corn cobs with 0.6% H2SO, and sawdust with 0.8% H2SO4 at 122.0§C for 60 minutes increased their reducing sugar contents. Candida pelliculosa P6 was the most active strain utilizing the three tested agricultural residues. It gave the highest growth density of 7.5, 9.0 and 21.75 g dried cells litre[-1] on sawdust, bagasse and corn cobs respectively, Chemical composition of the most active strains of yeast were studied
